gn format: 80-character comment wrapping and reflowing improvements

Implement intelligent paragraph reflowing that triggers when lines
exceed 80 characters. Heuristics protect URLs, indented code, pragmas,
numbered and bulleted lists and preformatted blocks from reflowing.
Single-word paths and targets are also isolated. Attention markers like
TODO or NOTE also force distinct paragraph breaks.

20 new tests are added to verify all the new behavior against wrapping
scenarios seen in Chromium code base.

This latest gn format was run on Chromium's build files and verification
was done to ensure no pathological formatting anomolies were observed.
In addition, ninja output files were compared before and after and found
to be identical.
